Thanks @tmatheson-arm! I'll merge this as soon as #96478 gets merged - there, we introduce `AARCH64_PAUTH_PLATFORM_LLVM_LINUX_VERSION_INITFINIADDRDISC = 7`, so signed GOT should be bit 8. We can't use bit 8 for signed GOT right now since the implementation relies on contiguous set of flags - so, I'll wait for #96478 and change signed GOT bit position to 8.
